Harmonizing physical and IT security levels for critical infrastructures
(SICHERHEIT 2018, 2018) Chille, Vanessa; Mund, Sybille; Möller, Andreas
We present a concept for finding an appropriate combination of physical security and IT security measures such that a comprehensive protection is provided. In particular, we consider security for critical infrastructures, such as railway systems. For classifying physical security measures, the so-called Protection Classes from the standard EN 50600 are used in our approach. To provide comprehensive protection for a system under consideration, these sets of explicit physical security measures need to be combined with other kinds of security, such as IT security and organizational security. We present a new classification approach named 'Type of Attack(er)' that allows for taking all aspects of security into joint consideration, and harmonizes physical and IT security levels by creating a link between EN 50600 and IEC 62443.
